There is what we call diversification in crypto, I want to believe you already know what that means.?
Now, you can try to apply that in your strategy, you don't have to go all in on Bitcoin and you don't have to go all in on altcoins, share your portfolio between the two, but make sure you have a higher portfolio on Bitcoin since it's  the safest, altcoins do have a better return on investments, but also do not rule out the fact that they are highly risky and can swallow your money in just a matter of seconds, take what happened to Terra Luna as a point of reference, alot of altcoins have come and gone, but bitcoin remains and still standing strong.

So my advice is, if you are in need of quick profit and must buy altcoins, make sure you have a higher percentage of bitcoin in your portfolio.
